Similar to the case file format, parentheses bound the various pieces of information in the formatted, ASCII file. The title
(title " ") and labels
(labels " ") must be first in the file, then each curve has information in the form
((cxvar value) x y x y x y ...), where there may be zero or more
Cortex variables defined for each curve.

You do not have to include
Cortex variables to import your XY data. For example, you may wish to import experimental data to compare with the
FLUENT solution. The following example would use the default
Cortex variables in the code to define the data. After you import the file into
FLUENT, you could then use the
Axes panel and the
Curves panel to customize the XY plot, as described in Sections
28.8.8 and
28.8.9.
